Ensure there are no obstructions and that the fans are operating. Before turning the unit back on, let it cool, remove any obstructions, and inspect the fans.
How can you verify the ViewSonic projector’s viewing hours?****
In the OSD Menu, you can monitor the projector light life. You may access the Lamp settings by selecting Lamp from the Advanced Settings menu after opening the menu. You might need to look in Settings or Options for this information on some projectors because it may be in a different place.

Why is my ViewSonic screen black?****

Can the projector be left on all night?****
A projector can be left on all night, although it’s not advised. It’s recommended to turn off or set a projector to blank mode when it’s not in use. The lifespan of the lamp is increased as a result. There is no issue with leaving your projector on overnight, just like when you use it all day.

bellows or lens blower, which are easily accessible at camera shops. Use a
lens cleaning tissue together with a tiny amount of lens cleaning fluid, or
gently wipe your lenses with a lens cleaning cloth.

I just got my PX701 4K, and it definitely supports 3D. It looks really darn good and was a fantastic surprise. I have 1.05 firmware for it. My wall can be projected off of using my old dlp sync glasses.
Does the X1 model’s refresh rate enable 1080p 120hz for the Xbox Series X?****
120Hz at 1080p is supported by the X1. Although the XBox Series X should theoretically support this resolution and refresh rate, not all displays are guaranteed to be able to use these settings with the XBox. You may also need to adjust the XBox to use it outside of 1080p/60hz.
